Stefan Weil 95d5f08bad Documentation: Add missing texi description for command line options
Some more command line options had entries for command line help,
but documentation for texi and derived formats (man, html, info)
was missing.

For conditional options, the texi documentation was added
unconditionally.

This seems reasonable because typically man pages are
shared, and html users expect to see one documentation
(not several nearly identical documents for the different
systems).

Stefan Weil 922910ce42 qdev: Add help for property value
When called with property value "?",
a help text will be printed (instead of an error message).

This is useful for command lines like
    	qemu -device e1000,mac=?
and is already standard for other command line options.

A better help text could be provided by extending
the Property structure with a desc field.

Anthony Liguori ff06ea2197 json: escape u0000 .. u001F when outputting json
Markus Armbruster pointed out:

JSON requires control characters in strings to be escaped.  RFC 4627
section 2.5:

   A string begins and ends with quotation marks.  All Unicode
   characters may be placed within the quotation marks except for the
   characters that must be escaped: quotation mark, reverse solidus, and
   the control characters (U+0000 through U+001F).

We've been quoting the special escape sequences that JSON defines but we
haven't been encoding the full control character range.  This patch fixes that.

A new option, -nodefconfig is introduced to prevent loading from the default
config location.  Otherwise, two configuration files will be searched for,

To ensure that the default configuration is overridden by a user specified

two lines down the descriptor is evaluated again, leaving us with an
